Problems with nvidia 440.60 dkms driver in CL 32600? Temporary Fix here

General Discussion
1

CL 32600 ships with GCC version 9.3.1, but the kernel-native-dkms module is still compiled with gcc 9.2.x. The default nvidia-installer command line performs a gcc version check between the kernel and the provided dkms module and complains when they diverge:

–no-cc-version-check
The NVIDIA kernel module should be compiled with the same compiler that was used to compile the currently running kernel. The layout of some Linux kernel data structures may be dependent on the version of gcc used to compile it. The Linux 2.6 kernel modules are tagged with information about the compiler and the Linux kernel’s module loader performs a strict version match check. nvidia-installer checks for mismatches prior to building the NVIDIA kernel module and aborts the installation in case of failures. Use this option to override this check.

Temporary fix: Add the --no-cc-version-check option in the installer command line to forcefully compile the driver.

Compiler version check failed:

The major and minor number of the compiler used to
compile the kernel:

gcc version 9.2.1 20200311 gcc_9_2_0_release-746-gc9858be2e7 (Clear Linux OS for Intel Architecture)

does not match the compiler used here:

It is recommended to set the CC environment variable
to the compiler that was used to compile the kernel.

The compiler version check can be disabled by setting
the IGNORE_CC_MISMATCH environment variable to "1".
However, mixing compiler versions between the kernel
and kernel modules can result in subtle bugs that are
difficult to diagnose.

*** Failed CC version check. Bailing out! ***
